Humming nosie when idling.

So I've noticed a kinda humming nosie from the engine bay. Sometimes it's super loud wen cold and sometimes it goes away completely. I bodied it more around 1300rpms.


I went to the dealer see what the specialist had to say...and

My intake is the problem.. That there is a whole or a leak in the rub. My wanrranty does not over that...

My question is...
Is that really the problem and has anyone else had this problem

Same noise or no ?

 

I hope not that's why I bought the intake. To get rid of the problem. And at first it did.
It was all good. And I think
I fixed that problem cuz it used to do
It on start up now it's only at 17kish
